DNA 'first proof' linking 'Boston Strangler' DeSalvo to victim Sullivan

12 July 2013 Last updated at 03:27 BST

US authorities say DNA evidence links a dead convict long suspected to have been a notorious serial killer to a woman murdered nearly 50 years ago.

The remains of Albert DeSalvo, who confessed to the Boston Strangler murders, will be exhumed to compare to DNA from the body of Mary Sullivan, 19.

DNA from DeSalvo's nephew matches a sample found on her body, police say. The "familial" match is the first hard evidence DeSalvo was the Boston Strangler.

Tim Allman reports.
